In advertising, a fear pattern is a sequence of fear arousal and fear reduction that is felt by the viewing audience when exposed to an advertisement,[1] which attempts to threaten the audience by presenting a negative physical, psychological or social consequence that is likely to occur if they engage in a particular behaviour. Fear appeals are commonly used in social marketing campaigns.[clarification needed] These are sometimes called “threat appeals”, however the label “fear appeals” is justified if the appeal can be shown to arouse fear.
